Cold Grinding, Cryogenic Milling

Cryogenic Milling is a process to reduce particles by means of mechanical force as well as embrittlement of the material by means of cooling by liquid nitrogen. Thus the fracture behaviour of viscous or elastic materials is transferred into the state that a grinding/ milling is possible.

With the cryogenic method specifically particle fineness can be achieved while maintaining product quality. Cooling of heat sensitive materials with liquid nitrogen during the grinding process prevents their temperature from rising during the mechanical grinding. The usual heating due to the grinding process is prevented which eliminates material melting and sticking.

A grinding under liquid and gaseous nitrogen is available on the following plants:
